Introduction to Profibus

Profibus (Process Field Bus) is a vendor–independent, open field bus standard thatis supported by leading manufacturers of automation products. A host of certifiedProfibus products are available, offering an array of products including sensors,motor drives and starters, PLCs, remote I/O systems, etc.Here are some Profibus concepts that you may find helpful.

• Profibus offers three types of profiles.• Process Automation (PA)• Fieldbus Message Specification (FMS) communication profile• Decentralized Periphery (DP)

• Profibus – DP is the most frequently used communication profile.• The H2–PBC is a DP slave• Master and slave devices, max. 126 stations on one bus

• Connection oriented communication• Transmission rate up to 12 Mbps

• Peer–to–peer (user data communication) or multicast (control commands)

• Cyclic master–slave user data communication• Control commands allow synchronization of I/O

• Methods for diagnostic and error detection are built into the system

PROFIBUS International (PI) maintains the PROFIBUS standard and providescertification to EN 50170 and IEC 61158 standards for devices. The main purpose ofcertification is to provide users with the assurance that devices from differentmanufactures will work in the same network. Certification is issued by thePROFIBUS Certification Centre in Karlsruhe, Germany.PROFIBUS Nutzerorganisation e.V.Haid–und–Neu–StraBe 7D–76131 KarlsruhePhone ++49 721 96 58 590, Fax ++49 721 96 58 [email protected]

Introduction


DP Communication Profile

The DP Communication Profile is designed for efficient data excahnge at the fieldlevel. The central automation devices, such as PLC/PC or process control systems,communicate through a fast serial connection with distributed field devices whichcan be I/O, drives and valves, as well as measuring transducers. Data exchangewith the distributed devices is mainly cyclic.The master controller cyclically reads the input information from the slaves andcyclically writes the output information to the slaves. The bus cycle time should beshorter than the program cycle time of the central automation system, which formany applications is approximately 10 msec. In addition to cyclic user datatransmission, DP provides powerful functions for diagnostics and commissioning.Data communication is monitored by monitoring functions on both the master andslave side.DP requires only about 1 msec at 12 Mbit/sec for the transmission of 512 bits of inputdata and 512 bits of output data distributed over 32 stations. The chart below showsthe typical time, depending on number of stations and transmission speed.Transmitting the input and output data in a single message cycle with DP, results in asignificant increase in speed compared to FMS.

Introduction


Below is a small glossary of terms used in this manual.

Mono–Master Only one Profibus master active on the bus duringoperation of the bus system of which the H2–PBC is a slave. This can be either a PLC module or a card in your PC.

Multi–Master Several Profibus masters are connected to one bus. These masters represent either independentsubsystems or additional configuration and diagnostic devices.

Slave a peripheral device (I/O devices, drives, HMI, valves, measuring transducers) which collects input information and sends output information to the peripherals. The H2–PBC is a slave which is also referred to as a controller in a Profibus I/O sub–system.

Segment One bus structure with a maximum of 32 stations (master or slaves) or nodes. A maximum of 9 segments is possible with the use of repeaters.

Station A node. Can be a master or a slave.

Repeater An RS485 device that amplifies data signals on bus lines and is the link between individual bus segments. Used to increase the number of nodes or to extend the cable lingth between two nodes.

Node Address The unique device address on a Profibus network. There are a maximum of 126 (0–126).The master is usually node 0.

Token The bus access right which is assigned to each master within a precisely defined timeframe.

Installation and Setup


Installing the H2–PBC

Setting the Node Address

Profibus DP is usually a mono master system. Since Profibus is based on a tokenprinciple, more than one active station (masters) is allowed. The overall controllingmaster of the network should be node address “1”. The master should be placed atthe beginning of the network. Network address “0” should be reserved for monitoringand diagnostic devices.It is recommended that slave devices begin with address “3”. The slave devicesneed to be addressed in consecutive order by bus location moving away from themaster.Locate the DIP switch on the module and set the Node Address to an available NodeAddress, from 3 – 125 for the H2–PBC. Node Address 0 is normally reserved for theProfibus network master. Note that each DIP switch position is numbered on theprinted circuit board, beginning from the right, 0 (zero) through 7. Each DIP switchposition represent the power of 2. Refer to the figure below.

The Node Address equals the sum of the binary values of the slide switches set in theON position. For example, if you set slide switches 1 and 3 to the ON position, theNode Address will be 10. This is found by adding 8+2=10. The maximum value youcan set on the DIP switch is 32+16+8+4+2+1=63. This is achieved by setting switches0 through 5 to the ON position.

The Profibus Network

RS–485 serial communication is most frequently used by Profibus. Twisted pairshielded copper cable with one conductor pair is the most common cable used forthe Profibus network. Installation of this cable does not require expert knowledge.The bus structure permits addition and removal of stations or step–by–stepcommissioning of the system without interfering with the other stations. Laterexpansions will not effect the stations which are already in operation. It is importantto follow the RS–485 installation guidelines, for 90% of the problems which occurwith Profibus networks can be attributed to incorrect wiring and installation.

All devices are connected in a bus structure (line) in a Profibus network. It can bebuilt in several segments with a segment consisting of the maximum number ofstations (32) and/or the maximum length of the network. A repeater must be added ifthere is a need to have more than 32 stations (126 maximum). The bus is terminatedby an active bus terminator at the beginning and end of each segment. See thediagram of the termination network below. Both bus terminators should be poweredat all times to insure error–free operation. The bus terminator can usually beswitched at the device or in the bus terminator connections.

Communication speeds between 9.6 kbps and 12 Mbps are available. One uniquebaud rate is selected for all devices on the bus when the system is commissioned.The baud rate selected will depend upon the cable length.The following table shows the maximum network cable lengths for the availablebaud rates that can be obtained with copper wire.

To use baud rates greater than 1.5 Mbps, special connectors are required. Theconnectors have built in inductors in order to run with higher baud rates (refer to thediagram on page 2–9). Branch lines are not permitted when using baud rates greaterthan 1.5 Mbps. The minimum recommended cable length between two stations is1m/3 feet.The standard EN 50170 specifies the cable for use with Profibus. The following tablespecifications must be met for Profibus cables.

There are several types of Profibus cable available. The most common cable usedhas solid conductors for the Profibus line. Some recommended cables are: two withsolid conductors, Belden Profibus 3079A and Siemens 6XV1 830 0AH10, one withflexible conductors, Bosch Comnet DP #913 548.The Profibus network is generally connected with a shielded, twisted pair, cable. Theshield must to be connected to the protective housing of the connector which is thenbrought to ground through the connection on the device. Care must be taken whenconnecting the wires to the connectors that the shield and wires are properlyinstalled.

In many automation control systems, the I/O bus cables are the most importantconnections between individual components in the system. Damage to the cable orimproper cable installation can lead to problems and often to a breakdown of theentire control system.To avoid damage to the Profibus cables, install them where they will be clearly visibleand separate from all other cables. This will improve EMC characteristics. Install thecables in their own cable trays or conduit separate from all A/C power wiring.The standard Profibus cable is intended for permanent installation in buildings or inan environment which is protected form the climate. The cable should only be usedin applications where there is a minimum of cable flexing and where it will not beexposed to a wet environment.A 9–pin D–sub connector is required for connecting to Profibus networks usingRS–485 for communication. The connector pin assignment and the wiring is shownin the following diagram.

The two wires are usually color coded. Typically red and green are used. Red is usedfor the B Transmit/Receive line and Green for the A transmit/receive line. It isimportant to keep A and B line consistent throughout the network to avoid improperoperation. This is the most common connection mistake in the field.It is recommended that a IP20 protective connector, such as, the VerticalTermination shown in the diagram on the next page, be used for making allterminations for the Profibus network. This is the best way for a quick and easysolution to terminating each end of your Profibus network. AutomationDirect offerstwo certified connectors for the Profibus Base Controller, one for a standardtermination and one for a node termination.

One important point when setting up a Profibus network is where and how to placethe termination. Each Profibus peer–to–peer network, or last segment, needs to beterminated at the beginning and end of a segment (must be at the last device). Thetermination is usually built into the connector. Power must be supplied to theterminating resistors at the device. This means the last device needs to be poweredat all times. If you have to replace the last device, the whole network could becomeunstable. It is preferred that the master device be installed at the beginning of thenetwork and as a termination point.Each segment is allowed to have a maximum of 32 stations, and a maximum of 9segments is possible.For installation applications where there is electromagnetic interference or to coverlonger distances, fiber optic cable can be used for the Profibus field bus networks.Refer to Profibus guideline 2.022 for the specification of the Profibus fiber optictransmission method. For an overview of the fiber optic components available forProfibus, refer to a current Profibus Product Guide which can be found at theProfibus website, www.profibus.com.

Configuring the ControllerUse the Profibus configuration tool (this should come with the master unit) toconfigure the master and the H2–PBC for your network. Refer to the software Helpfile and/or the manual for assistance with the configuration.The actual configuration of the H2–PBC takes place whenever the Profibus masteris configured. The characteristic communication features of the H2–PBC aredefined in the form of an electronic device data sheet, GSD file. The defined fileformat permits the configuration system to simply read in the GSD files of theH2–PBC and automatically use this information when configuring the bus system.The GSD file is installed in the Profibus master during the configuration of themaster.

The configuration tool made available with the master controller will allow you toachieve a simple Plug and Play configuration for your Profibus network. Based onthe GSD files, the network can be set up with devices from different manufacturers.

1. Set the Controller Node Address:Make sure that the H2–PBC Base Controller node address is set to anavailable node number on the Profibus network (from 3 to 125).

2. Configure the Profibus master:Configure the Profibus master with the Profibus Configuration Tool thatwas supplied with the master controller to configure the H2–PBC and theDL205 I/O.

3. Add the GSD file:When configuring the Profibus master, add the H2–PBC slave GSD filefrom the disk which came with this manual or from our web sitewww.automationdirect.com.

4. Commission the Node:Use the Profibus Configuration Tool used to configure the master to put thesystem on line.

5. Scan the I/O:Use the monitor utility that comes with the configuration tool to scan theDL205 I/O.

6. View Indicators on the H2–PBC module:Refer to the Status Indicators when connecting to the network.

The Profibus DP slave memory map specification per station will allow up to 244bytes of input data and 244 bytes of output data to be transmitted. This is well withinthe range for the DL205 I/O modules. The H2–CTRIO module will be limited to nomore than four modules per H2–PBC station due to the power budget restraints.

Calculating the Power Budget for the DL205 with H2–PBC

When determining which I/O modules you will be using in the H2–PBC system, it isimportant to remember that there is a limited amount of power available from thepower supply. A table has been provided here showing the power available from thevarious DL205 base power supplies and a table showing the maximum powerconsumed by the H2–PBC and each of the I/O modules supported by the H2–PBC.Following these two tables is an example of a completed power budgetingworksheet and then a blank worksheet you can use for your own calculations.

If the I/O modules you choose exceed the maximum power available from thesmaller DL205 base power supplies, you will need to use a D2–09B 9-slot base. Thisbase supplies more power than the other bases, as you can see in the table below.

WARNING: It is extremely important to calculate the power budget. If you exceedthe power budget, the system may operate in an unpredictable manner which mayresult in a risk of personal injury or equipment damage.

The following table shows the amount of electrical current available at the twovoltages supplied from the DL205 base. Use these values when calculating thepower budget for you system.

The Auxiliary 24V power source mentioned in the table is available at the baseterminal strip. You can connect to external devices or DL205 I/O modules thatrequire 24VDC, but be sure not to exceed the maximum current supplied.

More information about the purchase of this card canbe obtained from their website, www.mySST.com. The PC used for the setupprocedure explained here uses this interface card. Whenever this card has beeninstalled, run the SST Profibus Configuration Tool to configure the Profibus cardbefore beginning the Think & Do setup.

The following setup uses Think & Do Studio; however, if you have Think & Do LIVEinstalled on your PC, you will use I/O View instead of the Connectivity Center tosetup the H2–PBC DP Slave on the network.

First, Be sure that the Node Address has been set to a proper address (3 to 125 forthe H2–PBC). Next, open Think & Do Studio and select File > New in the ProjectCenter window. Use the following procedure to setup the H2–PBC with Think & DoStudio. The procedure assumes that the Profibus cable is connected from the SSTcard to your H2–PBC Profibus Base Controller with Terminator I/O installed.

1. Rename the project (the example name is PROFIBUS).

2. Click on the ConnectivityCenter button.
